To all whom it' may concern:

Be it known that l, EDWIN Gr. Bosse, a citizen of the United States.,residing at Chicago, Illinois, have invented a certain new and usefulimprovement in Supporting Spring Mountings, of which the following' is afull, clear, and enact description, such as Will-enable others skilledin the art to which it appertains to make and use the saine, referencebeing.;v had to the accompany@ ing d1 awings, forming part of thisspccilicatinn Ti s invention relates to railway truclr equi/ment, andparticularly to an improved arrangement for mounting the conventionalthird and fourth point supporting springs9 which are commonly used inassociation. with brake rigging to provide a forward guide and a safetysupport :for the brake beams.

The object of the present improvement is to provide an arrangement formounting the supporting springs on the spring plank in such fashion thatthey may be properly and securely maintained in operative position, andyet may be quickly and easily when desired, to facilitate unhanging ofthe brake beam or making,f otherrepairs to asso- 'ciated truck portions.

As is Well lrnovvn in present practice, itirequently occurs, whenrepairs are being; inadel upon the brake beam or other truck portions,that the third or fourth point sup porting springs, if permanentlyaffixed to the spring plank, are bent down to an in operative position4by the workmen, and then are not restored to operativo t if they areremovably inounte frequently arenot replaced after repairs are made. Bymeans of the present improvement, l provide. a form of mounting in whichthe rel Inoval and the replacementiloi the supporti ingsprings are soeasily accomplished that no temptation is offered a Workman 4to avoidthose operations. The arrangement is de signed particularly for thoseforms oi? spring plank;- and supporting springs in which the latter areshaped for the accommodation of the spring plank or parts thereof sothat the supporting springs cannot be removed by longitudinal movementor by rotary more removed,

osition; or.

l and having its outer entremit nient but may bo removed by bodilymovement longitudinally of the spring4 plank.

'ln the accompanying drawings, the vari4 ous forms in which theinvention may he embodied are shown, Figure l being a partial sideelevation of a third or i'oiiith point eupporting,P spring shown inassociation. with the spring plank, the latter being 'shown in sectionand equippedv with one form oi? my improved attaching arrangement.

lin each oi' the several illustrations, the corresponding parts areindicated by similar reference numerals, the numeral l designating thespring plank which is of conventional fciiannelA form, and upon which.the third or fourth point supporting spring 2 is carried. The spring isVbent to accommodate the lateral fianges of the spring planks and so asto maire contact with the upper surface of' the plank intermediate thelateral flanges. The extremities of the spring entend outM vvardly 'fromopposite sides of the spring plank in the usual fashion for thecustomary association with the brake beanie.i Mounted on the upper sideof the springjplank are bracket members la each having'a portion lispaced away from the upper surface of elevation 0i a the spring plankfor the reception and ac4 commolation of the supporting spring, shapedto fal cilitate the insertion of t. o supporting spring thereunder'. Thebracket i forms a stop which limits the movement of the spring in onedirection longitudinally oit' the spring pla/nh'. Mounted on the springplank in association with the bracket l` is a enibie or elasticretainirifg= mein-ber shaped with a portieri 5f* which is adapted toengage the spring; 2 under the normal tendency of the the retaining;member is (Y 'tmnsmit-ted io ne spring piani; iezl.
